Windows 7 tcpip.sys Auto Patcher to Remove TCP/IP Connection Limit

All version of windows has typical network related file tcpip.sys which has a half connection limit in itself, which doesn’t allow more than 10 half open connections to be made simultaneously. This has been designed to make your connections more stable and your network more responsive to all computers attached to it.
However if you are frequent p2p & bittorent user or surfing the internet heavily, then this limit may create connection errors or result in connection dropping. TCP-Z is the only program which automatically patches tcpip.sys file to remove TCP connection limit.
TCP-Z has been upgraded to latest version 2.4 Build 20090108 to support 32-bit and 64-bit (x86 and x64) version Windows 7 operating system.TCP-Z is gui utility and patches tcpip.sys to increase limit imposed on concurrent half-open outbound TCP connection attempts.

I was under the impression this was done for security reasons as well, not stability.

Don't use this crap anymore. 7068 lifted the limit to 120.

Didn't they include a registry hack you could to to manually set the limit as well?

Yes they did

Patching the TCP-IP stack or tcpip.sys file is a MASSIVE security risk, How can you be sure they didn't just open your entire networking stack for accessing your machine??

Users can change the limit to any value by navigating to the following registry key:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\]

Locate “TcpNumConnections” registry value and change its value data to number you want.

So will this help out in BitTorrent throughput or is just really negligible?

Negligible. Remember this only restricts "half-open" connections, not connections in general. Half-open connections are those in process of connecting, when one endpoint has ACK'd but the other hasn't yet.
